Something that is useful at the highest level of 2x2 is knowing multiple algs to skip pre AUF or post AUF. I have various algs to skip both of those as it can come in very handy. The top alg for each case may not be the best case for you. Make sure to look at the options and figure out which one works for you.

Many algs on my website have been found by myself and probably every other single world class 2x2 solver. Not every single alg was discovered by me. Thanks to all who continue to find amazing algs! :)
